grid起图形安装rac，跨网段

安装关键包如下： 

 yum install xorg-x11-xauth xterm -y

使用xshell报错：

[grid@rac1 grid]$ ./gridSetup.sh 
ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyinfo exist under PATH variable.

No X11 DISPLAY variable was set, but this program performed an operation which requires it.
[grid@rac1 grid]$ export DISPLAY=10.168.20.66:0.0
[grid@rac1 grid]$ ./gridSetup.sh 
ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyinfo exist under PATH variable.
改为使用xstart,新建xstart即可：
